; Instcombine was missing a test that caused it to make illegal transformations
; sometimes. In this case, it transforms the sub into an add:
; RUN: echo foo
; RUN: llvm-upgrade < %s | llvm-as | opt -instcombine | llvm-dis | not grep add
;
int "test"(int %i, int %j) {
%A = mul int %i, %j
%B = sub int 2, %A
ret int %B
}
